Video game collecting is something that's taken very seriously by some, and there are hundreds of expensive eBay auctions to back it up. The latest example to catch our eye is a listing on Game Gavel, with a very unique game and console up for auction.

On sale is a copy of SNES Campus Challenge, a custom made cart from Nintendo, which was used to host video game competitions on various college campuses throughout the early '90s. The game features levels from such classics as Super Mario World, F-Zero, and Pilotwings, and players are tasked with collecting 50 coins in Super Mario World, completing two laps in F-Zero, and land on two targets in Pilotwings.

Very few copies of this cart exist today, although reproduction carts have surfaced online. The other item up for sale is a custom built SNES, which runs both NTSC and PAL games - although NTSC games will need to be slightly modded in order to fit them into the cartridge housing.
